目的:确立时间分辨荧光方法检测血清乙型肝炎病毒(乙肝)表面抗原(HBsAg )、乙肝表面抗体(HB‐sAb)、乙肝e抗原(HBeAg)、乙肝e抗体(HBeAb)以及乙肝核心抗体(HBcAb)(俗称乙肝两对半)的检出限(LOD),以指导其检测结果的合理解释与应用。方法参考美国临床检验标准化委员会(CLSI)EP17‐A文件提供的方案和相关文献,建立实验室时间分辨荧光分析仪检测血清乙肝两对半的空白限(LOB)及LOD。结果时间分辨荧光分析仪检测血清乙肝两对半中 HBsAg、HBsAb、HBeAg、HBeAb、HBcAb的 LOB分别为0.0425 ng/mL、0.5005 mIU/mL、0.000 PEIU/mL、0.997 DRU/mL、0.091 DRU/mL ;LOD分别为0.163 ng/mL、1.203 mIU/mL、0.401 PEIU/mL、1.756 DRU/mL、0.350 DRU/mL。结论时间分辨荧光方法检测血清乙肝两对半,均有较低的检出限,可较敏感地检出血清乙肝两对半中的各项抗原及抗体,早期指导临床对乙型肝炎病毒感染的诊断、疗效的观察及预后的判断。
目的:確立時間分辨熒光方法檢測血清乙型肝炎病毒(乙肝)錶麵抗原(HBsAg )、乙肝錶麵抗體(HB‐sAb)、乙肝e抗原(HBeAg)、乙肝e抗體(HBeAb)以及乙肝覈心抗體(HBcAb)(俗稱乙肝兩對半)的檢齣限(LOD),以指導其檢測結果的閤理解釋與應用。方法參攷美國臨床檢驗標準化委員會(CLSI)EP17‐A文件提供的方案和相關文獻,建立實驗室時間分辨熒光分析儀檢測血清乙肝兩對半的空白限(LOB)及LOD。結果時間分辨熒光分析儀檢測血清乙肝兩對半中 HBsAg、HBsAb、HBeAg、HBeAb、HBcAb的 LOB分彆為0.0425 ng/mL、0.5005 mIU/mL、0.000 PEIU/mL、0.997 DRU/mL、0.091 DRU/mL ;LOD分彆為0.163 ng/mL、1.203 mIU/mL、0.401 PEIU/mL、1.756 DRU/mL、0.350 DRU/mL。結論時間分辨熒光方法檢測血清乙肝兩對半,均有較低的檢齣限,可較敏感地檢齣血清乙肝兩對半中的各項抗原及抗體,早期指導臨床對乙型肝炎病毒感染的診斷、療效的觀察及預後的判斷。

Objective To establish the limit of detection(LOD) of hepatitis B surface antigen(HBsAg) ,Hb‐sAb ,HbeAg ,HbeAB and HBcAB by using the time‐resolved fluorescence immunoassy (TRFIA) in order to guide the reasonable interpretation and application for their detection results .Methods Referring to the scheme and the related literature provided by the EP17‐A document of CLSI ,the limit of blank(LOB) and the limit of detection(LOD) of the hepatitis B serological markers by using TRFIA were established .Results LOB of serum HBsAg ,HbsAb ,HbeAg , HbeAb and HBcAb was 0 .042 5 ng/mL ,0 .500 5 mIU/mL ,0 .000 PEIU/mL ,0 .997 DRU/mL and 0 .091 DRU/mL respectively ;LOD was 0 .163 ng/mL ,1 .203 mIU/mL ,0 .401 PEIU/mL ,1 .756 DRU/mL and 0 .350 DRU/mL re‐spectively .Conclusion TRFIA for detecting serum hepatitis B serological markers has the lower LOD ,can more sen‐sitively detect each antigen and each antibody of hepatitis B serological markers and early guide clinical diagnosis of hepatitis B virus infection ,efficacy observation and prognosis judgment .
